Bluetooth Keyboard Keeps Dropping Connection

I started using a USB wireless trackball I purchased

USB or Wireless?

* First thing to do, check the batteries in the keyboard. Replace with fresh ones just for testing (even if your others seem okay, you can always swap back later).
* Try using the keyboard without the trackball. See if it still does it? If it does it may be the Keyboards fault? Try it on a different Mac.
* If it doesn't do it, try using it again with the Trackball. If it does it then, it's likely an issue between the two of them.

It could be coincidental, and its easy enough to eliminate the USB dongle based wireless trackball as the cause. Simply unplug the USB dongle and use a regular USB mouse or trackball, and see if the keyboard still has issues.

Assuming you've already made sure your batteries are fresh in the keyboard, have you checked Console for anything? Did you recently apply any Software Updates, like going from 10.5.6 to .7 or .8? Those updates caused a failure of proper support of some Bluetooth chipsets, resulting in behaviors like you describe. (I know this personally, the update broke support for my BT mouse.)

You can't be sure how long that keyboard has been sitting in the store. Maybe it's been there a while and the batteries depreciated.
